Abstract
Simple expressions, suitable for design purposes, are deduced for the major aberrations due to the magnetic deflection of the convergent electron beam in a cathode-ray tube. These expressions are confirmed by measurements on a number of saddle and toroidal scanning coils. Conditions are derived for an anastigmatic display.
